I'm coming around to the safety thing...maybe a hybrid safety/corner.
IMHO, he just isn't a corner. He's a good football player though and should be on the field in some shape form or fashion. Unfortunately, it just looks like he may be a tweener.
Maybe have him put on another 10 lbs or so and try him at safety next year? Maybe be a nickle/dime safety?
Even last week, we all thought he had a good game with the 11 tackles, but corners making that many tackles means that they are completing a lot of passes on you.
I wasn't big on the safety thing before due to his size, but I mean it's apparent to me that he is a good football player, just not that good of a corner...so we may have to find other ways to use him.
